WATER-HEATING SYSTEM SPECIFICATION forming part of Letters Patent No. 598,327, dated February -1, 1898. Application led April 20, 1895. Serial No. ML/L85. (No model.)

i To all whom it may concern.-

Beit known that I, OLIVER SGHLEMMER, a citizen of the United States, and a resident ofthe city of Cincinnati,in the county of Hamilton and State of Ohio, have invented certain many other results, some of which are to save the number of joints and extra piping, to diminish leakage, and reduce the Weight of the whole system, obtaining a compact system free from all of the objections consequent upon the employment of extra piping and devices now employed to accomplish the same result.

In order to accomplish the objects of my invention, it consists of a novel device and arrangement, all of which will be more fully understood with referenceto the accompanying drawings, in which similar parts are represented by similar letters throughout the several views.

Figure l represents a series of radiators.

with pipe connections provided with my ,improved device; Fig. 2 represents a vertical central sectional View of the device embodying my invention; and Fig. 3 represents a radiator provided with my improved device, showin g how the same may be employed when the dow of water is from above.

The pipe-fitting as embodied in my invention is represented by D. Assuming that the feed-water comes from below, D4 represents the entrance-openin g to the fitting, into which the feed-pipe A is to be screwed. Directly above this entrance-that is, in the same axial line with the opening D4-is an opening D5, into which is screwed the upwardly-extending feed-pipe A. On the left of the fitting, as shown in Fig. 2, is another opening D6,into which is screwed the local feed-pipeA.

Hindicates the entrance-passage to the fitting D.

The openings D4 and DG are connected by the passage F and the openings D4 and Dby the passage E.

The mouth of the passage F lies beyond the entrance H and in a direct axial line therewith. The passage F from the point where it meets the entrance H is continued on and curved to one side ofthe fitting in a direction at right angles to the axial line of the 'tting D and passes into the opening D6. The passage H at one side opens into the passage E. This passage E passesout to one side (to the right in Fig. 2) of the passage I-I and axial line of the fitting upward and again back into the axial line, when it connects with the opening D5 at K. For the formation of this passage F the casing of the fitting is extended outward, as at D2.

I am enabled to obtain the arrangement of the water-passages as shown by the peculiar construction of the walls of the fitting in combination with an interior diaphragm G, This diaphragm crosses the interior of the litting and the line of feed in the water-pipe in an oblique direction. The diaphragm is formed integral with the fitting, beginning above the opening D6, extending outwardly and downwardlyacross the axial line, and ending at G2 on the right in Fig. 2 of the axial line of the fitting and below the lowest point of the opening D6.

Just above the opening D4 and on the same side of the ttin g as the passage E is a delecting-liange G3. ing through the pipe A in the direction of the 1I arrow l will naturally have a tendency to conitinue its movement in a direct line coincident Thus the hot waterV passwith the axis of the vertical feed-pipe. Then it will pass to the left of the diaphragm G,Figs. il and 2, and enter the passage F.

The water willthen be deflected by the curve of the diaphragm G and pass' through the local feedpipeAinto the radiator connected therewith.

The Water is assisted in its deiiection through the passage F by the iiange G3. That portion of the hot water in feed-pipe A passing up on the right-hand side of the pipe A, Figs. l and 2, is deilected across the passage H toward the left, and therefore has a tendency to guide and throw the water passing with it toward the wall D3, and thus more IOO fully insure the delivery at the proper time of the entire bulk of hot water into the passage F. y

After the hot water has passed through the passage F and through the pipe A into the adjacent radiator C it will return through the return-pipe B to the heater. As soon as the radiator O has become lled with water and a cur.- rent established therein the water will meet with more resistance in passing through the pipe A into the passage F. Therefore a portion of the feed-water will pass to the right, entering the passage E and thence through the opening D5 into the feed-pipe, and will then continue on to the next radiator above if they are arranged as shown in Fig. l,where Y', Y2, and Y3 represent a series of iioors.

When the radiator connected to tting D isfilled, the currents of hot water will 'flow as indicated by the arrows in Fig. 2, the main volume will pass on in the direction of the arrow l and, if the radiator be filled, will divide, a portion taking the course of the arrows 2 and 3 and a portion the course of the arrows 4E and 5. When for any reason it becomes desirable to have the hot water delivered from above downward through the vertical pipes to the radiators, the system is reversed and the fitting will then be located substantially as shown in Fig. 3. In such even the former feed-pipe may become the return, as indicated. The hot water passing down through the feed-pipe A is deflected by means of the diaphragm G of the upper fitting, Fig. 3, into the radiator through the pipe A4. The hot water passes into the radiator, heatin git, and coming out below through the pipe B passes into the lower fitting D, Whose diaphragm deflects the water downward, substantially as shown. At the same time all of the hot water in the upper portion of the feed-pipe which does not enter the radiator C passes down the feed-pipe A and passages E and downward, mingling (below the section of the pipe-fitting D) with the water coming from the radiator, and passes down to the next radiator, if any, to be heated. By the means shown and described I am thus enabled to combine the feed-pipe in very compact form. l

Among the obvious advantages to be derived from a use of my invention are a perfect and even circulation of the hot Water through the system of pipes, an even distri-- bution of hot water to the various radiators, and consequently an even distribution of heat throughout the building -to be heated.

Other advantages are a saving of the number of joints from which connections are to be made. Thus, for instance, I employ but avoid cutting through the joist or other wood or metal work of the building or of so connecting as to make special provisions for piping necessary.

My invention secures all of the advantages l pertaining to the systems heretofore in use, together with many additional advantages,

vas specified.

It is obvious that I mayfmake such modifications in my invention as do not depart from the spirit thereof, and especially that the system and pipefitting may be used with steam or air instead of hot water.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a heating system, a hollow pipe-fitting vertically disposed, the main feed-pipe communicating with said fitting at its top and bottom, the branch feed-pipe communicating with said fitting at one side, said fitting having a iiange extending from its interior across the main feedpipe from a point above the branch feed-pipe, said flange being curved downwardly and extending below the branch feed-pipe and across the line of feed in the main pipe, the said flange forming in connection with the interior walls of the fitting the passages E and F, substantially as and for the purposes specified.

2. In a heating system, the combination of the hollow fitting vertically disposed, the Inain feed-pipe communicating with it at its top and bottom and arranged at one side of its axial line, and the branch feed-pipe coinmunicating with it at one side, said fitting forming a flange extending from. its interior across the main feed-pipe from a point above the branch feed-pipe and curved downwardly forming with the interior walls of the fitting the passages E and F, and said fitting being also provided with a fiange G3 arranged to de- .flect the fluid toward the passage F, substantially as described.
